comm 7 01. 105 -362) :This inventionrelatesgenerally'to car tank anchors and supporting means and more particularly to the provision of means-for anchoring and reinforcingly supporting tanks formed of material possessing high corrosion-resisting properties, such, for example, as aluminum, the present application being a divisionoimy pending application for United States Letters Patent, Serial No. 673,843-,'filed June 1 1933., I

sirable, and in some instances necessary, in the transportation of certain kinds-of liquid lading, but tanks formed of such material lack-tea great degree the desired strength and durability of more 'easily ccrrodible materials or metals, such, .forexample, as -steel or iron, and one" object ;of thisinvention isthe provision of'means for supporting such :a tank on itsunderframeand rein- ;forcing the same against deformation; v

A great disadvantage in the use of tanks formed of such; material been the ;difiiculty-.experi-' enced in providing means for adequately securing the tank to itsanchor and supporting means on the underframe w-ithout the use of objectionable rivets passing through the tank shell because of the necessity of forming the anchor and supporting means of a metal such for example, as steel, which possesses the required strength,- and it is well knownthat such metals as aluminum and steel cannot be effectively secured together Another object of this invention is the provision of means forgofiectively securing, bymeans ofrweldingta tank for-med of material possessing ,hizh corrosion 'resistingtproperties to its anchor and supporting means.

Btillanother object of' this invention is the provision of anew and improved means for supporting. a railway car tank'on' ah' underirame.

A further object or this invention is'the provision of anchor means for tanks of such construction as to avoid the use of rivets torsecuring the anchor means to the tank. thus eliminating the' possibility of leakage of; the contentshor .the tank at that portion thereof which is connected Other objects and advantages of'this invention will be apparent fromthe following description taken in conjunction with the accompanying drawings, in which Figure l is a side elevation view of a railway tank car embodyingthe anchor and supporting means of the present invention, certain parts The use of tanks formed o ffmaterial possessing high corrosion resisting properties is highly de-.

The underframe Balso includes cross bearers losecuredto the" center. 'SillS'Z'tl'ld extend the lower running boards 12 at each side ofthe car. of aluminum; and comprises a cylindrical shell 18, closed at its ends'by tank heads which are v Fig. 4: is an enlarged and broken sectional view 2 transversely therefrom whichv alsosupport The tank A, in the instance shown, is formed welded at 22 to the end portions thereoil- The welded joint 22 between the shell 18 and head 20 is reinforced by-an annular member ZA-Wh ich laps the joint and is welded. tothe shell 18. and head 20 at 26,,a1l as shown'inFig. 1, which construction provides a strong .and durable connec- 'tion between the shell and head.

1 The tank A is provided with external insular tion 28 covered by an outerv sheathing so'connected to the shell18 by anysuitable connecting or fastening means, such asthose shown at 32 in Fig. '2. Upper running boards 34 are alsopro- 'videdwhichare supported on brackets 36secure-d tothe outersheathing and'to which are connectedthe upper ends of the laddrs l' i. Y The 'ta'nk A is also provided Witli'a'fhaiid-rail 38 supported by brackets 40 securedto the o'uter-sh'eath- 1 ing 30, domes 42 having domecover's 44,;and-

also with discharge pipes 46, which lead to .dis-

charge valves (not'shown) The tank A adjacent its endportions'is supported on cradles 48 secured to'the bolsters 8,

said cradles including Wood block's 50,'as shown in Fig. 2; tank bands 52 secured to the cradles 48 in any desired manner; such as shown at 54, being provided for holding the tank on the cradles" '48.

Although in the instance shown the tank A is of a material which can be readily welded to" the tank shell, and being provided with ofiset' and anchor means to each other.

desirable to provide a reinforcing supporting or tank rest element for the tank A in the form of a curved platein'dicated'at 56 in Figs. 1, 2,

and 4, which extends longitudinally, of the under-- frame B and is substantially co-extensive with the tank A; said plate being preferably of a material possessing strength sufiicient to prevent easy deformation, such, for example,'as steel. cannot be readily welded to aluminum or other like metals and to attach the tank to said plate 56, fastening plates 58. are connected to the side edge portions thereof, intermediate the ends of the plate, as by rivets 60, these fastening plates being portions 62 welded as at 64 to saidtank shell. Intermediate the ends of the tank rest element 56 the tank A isanchored to the underframe B, as shown clearly in Fig. 4, said element 56 being 68 of a tank anchor, which may be of theform shown in patent to Auchincloss, 1,336,410, of April 13, 1920,; said tank anchor comprising an upper element'm'riveted as at '12 to the top flange 4 of each center sill 2; the side edge portions of said upper elements '70 being downwardly flanged or bent at 74 and riveted as at 76 to the depending on the wood blocks 50 of cradles 48, as clearly shown in Fig. 2, and asillustrated in Figs. land 3, the tank A adjacent its end portions is connected to the tank rest element by fastening plates 80 welded to the tank and bolted, as at '82, to the tank rest element, the bolts 82 passing through slots 84in the fastening plates, thus permitting longitudinal expansion of the tank A in service.

Intermediate the plates 80 and 58 the tank A is connected to the tank rest element 56 in a manner similar to that adjacent the end portions of the are used. i g r In the construction described it will be apparent that very effective means are provided'for securing a tank formed of material possessing high corrosion resisting properties to its anchor formed of steel without the necessity of employing rivets which pass through the tank shell and without resorting to directly welding the tank In theconstruction described it will also apparent that the tank A is efiectively" reinforced against deformation or collapse by the provision of the tank rest element 56 at the lower portion thereof.
